What is important to a facility, or studio, that is looking to hire a Yoga instructor? Teaching in a Yoga studio or an ashram is much different from teaching in a fitness center, church basement, senior center, or a condominium recreation center. The same can be said for the hiring requirements.
With all that said, it still looks professional to have a prepared resume, if or when, it is requested. Additionally, if you were to approach colleges, hospitals, retirement communities, or corporate fitness centers, you definitely should have a resume prepared. Many rewarding and steady teaching positions can be found outside Yoga schools in corporate, medical, fitness, community, and recreational facilities.
